LISTING-CULTIVATO R.

@PECEEICATION forming part of Letters Patent No. 329,530. dated November 3, 1885.

Application filed August 10, 1885. Serial No. 173,964. (No model.)

To all whom it may concern..-

Be it known that I, JOSEPH P. BLACK, a citizen of the United States, residing at Alton, in the county of Madison and State of Illinois,

have invented a new and useful Improvement in Listing-Cultivators, of which the following is a specification.

This invention relates to improvements in listing-cultivators of the same class as that patented to me March 17, 1885, and numbered 313, 847, and has the object of a greater amount of adjustability, and in providing that the beams may be hinged swinging inwardly or outwardly, as may be desired, and that the usual side bars, 0, as heretofore used, may be dispensed with or placed so far away and apart from the beams as not to obstruct or hinder the free movement or working of the beams.

The invention consists in certain improvements, combinations, and arrangements of parts,which will first be described in the specification, and afterward pointed out in the claims.

Referring to the drawings, like letters refer to like parts in all the figures, in which Figure 1 is a perspective view of my improved listing-eultivator, in which is shown how the beams A A are hinged direct to the cross plank B B and the heretofore usual side bars dispensed with. Fig. 2 is a plan or top view showing how the beams are hinged directly to the cross-plank and swinging inwardly. Fig. 3 is a plan or top view showing how the beams in their connection with the cross-plank B B maybe changed from that shown in Fig. 2 and the beams swinging outwardly instead of inwardly. Fig. 4 is a bottom, under, or reversed view, enlarged, of one of the beams A, showing how the blade H may be used therewith. Fig. 5 is a view, enlarged, of the hinge-joint J, showing how I preferably con- Struct it.

The frame may consist of the usual cross- 4 5 plank, B and B, with ends adapted to ride the ridges, and with the usual side bars, 0 O, bolted thereto, as shown in Figs. 2 and 3, or without the said side bars, as shown in Fig. 1, and with the usual draft-rod, D, as shown.

The beams A A preferably consist of planklumber, each two inches-thick by ten inches wide and four feet long, more or less, and one corner of their front end may be rounded, as usual.

In myimprovements I connect the beams A A directly to the cross-plank B B by a hingejoint in such a manner that the beam shall swing from one side or edge, as it were, as shown in the drawings.

Any ordinary flat strap hook-andeye hinge may be used in connecting the beams to the cross-planks. I preferably use a hinge-joint, as represented by J in the drawings, and shown in detail in Fig. 5, in which a represents a strap-hinge having at one end the hook I), and the, other end curved inward for a better support on the beam. The said strap may preferably extend across the end ofthe beam for holdingitl'rom splitting, and the curved end extend up the edge of the beam for giving a more 7Q steady or stiff support to the hook I), and in which 0 represents the eye or head part of the hingejoint. Said eye or head may be made of cast-iron, provided with the perforation m to admit the hook b, and the recessed perforation 7 u to admit the bolt d, for connecting to the cross-plank, as will be understood by Fig. 5; and the said eye 0, bolted to the said crossplank, and said strap a, bolted to said beams, directly connect the beams with the plank, and permit said beams to swing, as will be understood by the drawings.

It will be observed that the cross plank B B are provided with a series of perforations,

k, by which the beams A may be adjusted in moving the hingejoint so that the two beams may work either nearer together or wider apart, as will be understood by inspecting Fig.

2, in which the beams A A are represented as swinging inwardly, which is best suited for working the first and second time of listed planted corn. Then as the corn-plants get larger, and the valley in which the corn is growing becomes more or less filled, and the condition of things changed, it is desirable 5 and best to change the machine, moving the beams A A, as changing places with each other, and changing the hinge-joint so that the beamsshall swing outwardly; and in some cases, in which the valleys have been filled and the ground level, it will be advisable and best to bring the beams to a level working or to an incline for ridging, the reverse of working in a valley, in which the beams swinging outwardly will be'found best adapted; andit will be noticed that by the series of perforations h the beams may be adjusted wide apart or near together when swinging outwardly, as will be understood by inspecting Fig. 3.

It will be observed that the side bars, 0 (J, are placed at a distance away from the beams A A, which is that the said side bars may not obstruct the working of the said beams, as they sometimes do when near and the beams hinged thereto, as well known; and by reason of my improvements the side bars, 0 (J,- may be dispensed with and the machine operated without them, as shown in Fig. l, by which the machine is thought by some in its best trim or condition for working first times or when the ridges are in a very rough and uneven condition.

H represents my improved cultivatingblade, which I preferably use on this cultivator, consisting of a thin flat bar of steel having its front end twisted and provided with two perforations.

It is obvious that other shape and kinds of blades and harrow teeth, or a part blades and a part teeth, may be used in the place of my preferred blade without departing from the purview of my invention.

Other features and operations need not be herein described, as essentially the same are shown and described in my former patent above referred to.

Having thus set forth my invention, I claim as follows:

1. In a listing-cultivator, the frame having the cross-plank B B, adapted to ride the ridges, and the beams A A, connected directly to the said cross-plank by a hingejoint, permitting said beams to swing from one side, combined, arranged, and adapted to operate substantially as and for the purpose set forth.

2. In a listingcultivaltor, the combination of the two plank beams provided with blades or teeth for stirring the soil, the two crossplank adapted to ride the ridges, a hingejoint connecting the said beams directly to the said plank in such a manner as to permit the beams to swing from one side or edge, and an operating-lever adapted to swing the said,

beams, all substantially as and for the purpose set forth.

3. The cross plank B B, provided with the perforations h and perforations k, by which the beams may be connected to swing either inwardly or outwardly, as desired, in combination with the two plank beams, provided with a hinge-joint connecting directly to the said cross-plank, all substantially as and for the purpose set forth.

4.. The combination of the two crossplank adapted to ride the ridges, two side bars attached to and adapted to support the ends of said cross-plank, two swinging beams provided with blades or teeth, with a hingejoint directly connecting the said beams to the said cross-plank, substantially as and for the purpose shown.
